Quique uses his own unique A-frame design on the fuselage shape, which reduces flex in the more rigid fuselage giving you more precision control. From super slow to top airspeed, flying the Byp Yak features a great combination of smoothness and precision, helping make this foam Byp Yak an extreme 3D flying performer like no other foam airplanes of this caliber. The Byp Yak is capable of doing all the maneuvers that you have ever dreamt of and more. New Foam E-flite™ is introducing a new flat foam material with this aircraft. It is much more durable than other flat foams used in the past. We believe this will bring a higher level of success and enjoyment to your Byp Yak experience.

Place the fuselage on a flat surface. Use a square at the rudder to check that the fuse bottom and fin are square to each other. Lightly sand the bottom of the fuse where indicated if necessary. 10 2. Test fit the lower wing to the fuselage. Place the wing onto the fuse bottom, aligning the servo holes in the wing with the servo holes in the fuselage. Carefully check to make sure the lower wing is square to the fuselage by measuring from the wing tip to the fin on both sides. Use foamsafe CA to glue the lower wing to the fuselage. 3. Locate the wing struts. Use a sharp hobby knife to remove the lower sections from the main section. Note: You can use foam-safe activator to speed up the CA cure time. 11 4. Position the wing strut in the hole closest to the aileron of the bottom wing. It may be necessary to trim the reinforcement tape from the hole before fitting the strut. Use a square and foam-safe CA to glue both the wing struts into position. 5. Place the top wing onto a flat surface. Position the wing struts and fuselage onto the wing. Hold the wing flat while gluing the fuselage and side force generators to the wing. Note: It is recommended to use a square to check the wing strut alignment to the top wing. Note: DO NOT glue the lower strut extension at this time. 12 Note: You may want to locate a thin piece of Depron or other foam for the next section. A thin board will work too. This is necessary to keep the wing as flat as possible to keep from inducing any twist in the wing, which will greatly affect the performance of your Byp Yak. 7. Once the CA has fully cured from Step 6, slide a hobby knife into each of the reinforcements to make a thin slot. Do not cut an official slot; just slip the knife in and out. 6. Glue the strut reinforcement disks to the bottom of the top and bottom wings. The positions have been marked at the factory. The slots in the disks will run parallel to the spars. 13 8. Slide a .045" x 12 5/8" (1.15mm x 320mm) carbon rod from the center of the bottom wing to the top wing near the strut. Leave at least 1/16" (1.5mm) of the rod exposed at both ends. Glue the rod only at the fuselage. Apply foam-safe CA to the rod both at the inside and outside in order to capture the rod in position. 14 9. Place the top wing on a surface that will allow the wing panel to lie perfectly flat. Apply glue to the inside edge of the rod. Once the glue fully cures, carefully lift the airframe and apply CA to the top of the rod. 10. Repeat Steps 8 and 9 for the opposite side. 11. Slide a .045" x 13" (1.15mm x 330mm) carbon rod near the wing strut on the bottom wing to the center of the top wing near the fuselage. Leave at least 1/16" (1.5mm) of the rod exposed at both ends. Glue the rod only at the bottom wing. Apply foam-safe CA to the rod both at the inside and outside in order to capture the rod in position. 12. Place the bottom wing on a surface that will allow the wing panel to lie perfectly flat. Apply glue to the inside edge of the rod. Once the glue fully cures, carefully lift the airframe and apply CA to the top of the rod. 13. Repeat Steps 11 and 12 to complete the cross bracing. 15 14. Attach the remaining two strut reinforcement 15. Position two .045" x 6" (1.15mm x 153mm) disks to the inside of the struts. Once the CA cures, slide one of the .045" x 6" (1.15mm x 153mm) carbon rods from the center of the cross brace through the reinforcement. Carefully wrap the intersection using string. Soak the thread at the intersection with thin CA to secure the joint. carbon rods from the tips of the top and bottom wing to the center of the strut. Leave at least 1/16" (1.5mm) of the rod exposed on both ends. Apply CA to only the struts at the wing tips. Note: Do not glue the carbon rod at the strut at this time. 16 16. Use a straight edge to make sure the wing strut is not bent in or out on the wing. Glue both sides of the rod to the wing strut. 17. Repeat Steps 14 through 16 to complete the wing installation. 17 Stabilizer and Rudder Installation Required Parts • Fuselage • Right elevator • Rudder • Hinge tape • Stabilizer w/left elevator • Carbon elevator joiner (2) • Control horn (2) Required Tools and Adhesives • Foam-safe CA • Ruler • Paper towel/tissue • String • T-pins • Foam-safe activator 1. Use foam-safe CA to glue the plywood elevator horn into position. 18 Note: Ensure that the holes in the control horn are in line with the hinge line. 2. Slide the stabilizer into position, centering it in the slot. Sight from the rear of the fuselage and check that the stabilizer is parallel to the wings. If not, lightly sand the opening in the fuselage. 3. Hinge the elevator using the supplied tape. Apply tape to the hinge line on the top, and then deflect the elevator up to apply the tape on the bottom. 4. Use foam-safe CA to glue the carbon elevator joiner to the top and bottom of the elevators. Note: Make sure you are gluing the joiner directly onto the foam and not onto the hinge tape. 19 5. Check the alignment of the stabilizer to the front of the fuselage. The distances between a point centered on the fuselage to either stabilizer tip should be the same. 6. Once satisfied with the stabilizer alignment, use foam-safe CA to glue the stabilizer to the fuselage. Clean up excess glue with a tissue or paper towel. Note: You can use foam-safe Activator to speed up this CA cure time. 20 7. Use foam-safe CA to glue the plywood rudder horn into position 8. Test fit the rudder to the fuselage. Check that when the hinge line of the rudder is against the fuselage, the balance tab does not interfere with the fin. Note: Ensure that the holes in the control horn are in line with the hinge line. Note: Do not use CA on the hinges until you are sure the fit of the rudder is correct. 9. Once satisfied with the fit, apply 2–3 drops of foam-safe CA to each side of each rudder hinge. Work quickly to install the rudder before the CA has time to cure. 21 Motor and Speed Control Installation Required Parts • Airframe • Receiver • 3mm x 5mm screw (4) • 3mm washer (2) • Prop adapter • Hook and loop material • 10-amp electronic speed control • Propeller (10 x 3.8 recommended) • Brushless outrunner motor (EFLM1200 recommended) 1. To use an E-flite™ Outrunner, the shaft of the motor must exit the fixed part of the motor instead of through the rotating portion. You will have to change this. Loosen the setscrew in the rotating part of the motor. Slide the shaft though the motor and tighten the setscrew. Required Tools and Adhesives • Foam-safe CA • Phillips screwdriver (small) • Hex wrench, 3/32" Note: It is very important to check to be sure the propeller is balanced before installing onto the shaft. Note: Please follow the instructions included with your E-flite Outrunner motor for repositioning of the propeller shaft. 22 2. Attach the ESC to the motor. It may be necessary to solder connectors on the ESC. 4. Mount the motor, using four 3mm x 8mm screws and two 3mm washers. 3mm washers must be installed between the firewall and the motor on the pilot's right side to provide the correct amount of right thrust. 3. Check the direction of rotation of the motor using the radio system and motor. It should rotate counter-clockwise when viewed directly from the front. If it rotates clockwise, follow the instructions included with the ESC to correct the problem. Note: Please be sure to use an ESC with the proper 9V cutoff when using 3-cell Li-Po packs. We also suggest this cutoff to be of the soft variety to prevent hard motor cutoffs during low level 3D flying. 23 5. Attach the propeller using the propeller adapter included with the motor. Radio Installation Required Parts • Airframe • Cable crimp (8) • Servo (3) • Long servo arm (3) • Control cable • Hook and loop meterial • Micro control horn w/backplate (2) • Servo extension, 3" (76mm) • Micro cable adjust connector (4) • Aileron linkage, 5 3/4" (146mm) (2) • Aileron interconnect linkage, 9 1/4" (235mm) (2) • Micro control connector w/nylon backplate and 2mm x 3mm screw (8) Required Tools and Adhesives • Foam-safe CA • Pliers (for crimping) • Hot glue • Low-tack tape • Phillips screwdriver (small) 6. Secure the speed control location using doublesided tape or hook and loop. Exact speed control location may vary, depending on the brand used and the center of gravity. 24 1. Use hot glue to install the rudder, elevator and aileron servos. 25 2. Plug the elevator, rudder, aileron and ESC into the receiver and check their operation. Use hook and loop to attach the receiver to the inside of the fuselage. Use a short 3" (76mm) extension for the speed control if needed. 3. Route the antenna to the tail and then back up the opposite side of the fuselage. Do not cut the antenna as this will reduce the range of your radio system. 4. Install the six micro control connectors into each of the three long servo arms. Secure them using the control connector back plates. 26 5. With the radio system on, install the servo arms on the servos. Note: If you use the ESC to power your radio, be absolutely sure to remove the propeller to avoid injury. Note: Turn on radio system and verify all subtrims and flight trims are at zero or centered. 6. Locate the control cable and cut it into four equal sections. 27 7. Use tape to hold the rudder in neutral. Slide a cable crimp onto the control cable. The cable then goes through the horn, and back through the crimp. Use pliers to secure the crimp. Note: We recommend connecting the cable to the middle hole for the rudder control linkage setup. 28 8. Slide the micro cable adjust connector into the micro control connector and use a 2mm x 3mm screw to hold it in position. Repeat Step 7, installing the cable through the cable connector. 9. Remove the tape from the control surface. Install the second cable following Steps 7 and 8. Tension the cables lightly using the cable connectors to pull the surface into neutral. 10. Repeat Steps 7 through 9 for the elevator cables. Note: We recommend connecting the cable to the inner hole for the elevator control linkage setup. 29 11. Attach the micro control horn to the ailerons using the micro control horn back plates and foam-safe CA. 30 12. Pass the “Z” bend of the 5 3/4" (146mm) aileron linkages through the control horns. The opposite end goes through the micro control connector. With everything centered, secure the linkages using the 2mm x 3mm screws. 13. Attach a micro control connector to the horn on the top aileron. Make sure the hole for the screw faces towards the wing tip. 14. Pass the “Z” bend of a 9 1/4" (235mm) aileron interconnect linkage into the horn on the bottom aileron. Slide the linkage through the micro control connector, center the ailerons, and tighten the 2mm x 3mm screw. Hint: Lay a ruler from the leading edge to the trailing edge to check that the upper aileron is in neutral. 15. Repeat Steps 13 and 14 for the remaining aileron. 31 Landing Gear Installation Required Parts • Airframe • Landing gear • Tail skid • Wheel pant (2) • Wheel retainer (2) • 1 1/4" (32mm) wheel (2) • Landing gear fairing (2) 2. Install the landing gear into position by pressing up into the landing gear mount. Required Tools and Adhesives • Hot glue • Foam-safe CA 1. Glue the tail skid using foam-safe CA Note: Use a small amount of foam-safe CA if the landing gear is loose in the slot. 32 3. Install the landing gear fairings and wheel pants using hot glue. We recommend gluing the wire to the fairings only at the two ends. 4. Install the wheels using the wheel retainers and a drop of foam-safe CA on the end to secure the retainer. 33 5. Now that the landing gear has been installed, we can install the strut fences to the bottom of the bottom wing. They are angled 25 degrees towards the wing tip as shown. Center of Gravity / Battery Installation Required Parts • Airframe • Battery (480mAh, 3-cell, 11.1 V Li-Po, JST (THP4803SJ) • Hook and loop Note: A 730mAh 3-cell 11.1 V Li-Po (THP7303SJPL) battery can be used as an option to the 480mAh, 3-cell 11.1 V Li-Po battery. This battery will provide longer flight times. An important part of preparing the aircraft for flight is properly balancing the model. Caution: Do not inadvertently skip this step! Note: A template has been provided to achieve this angle. It is located on page 37. Please cut this template out and use it for alignment. 34 The recommended Center of Gravity (CG) location for the Byp Yak is 3 1/4" (82mm) behind the leading edge of the top wing. The battery is located as shown in the photo. Secure the battery using hook and loop material. It may be necessary to move either the ESC or receiver to achieve the correct Center of Gravity. Weights can be used if necessary, but will add to the overall flying weight of your model. This would be a last resort to achieve the correct CG. 35 Control Throws You may set your control throws up for a less sensitive setup for your first flights. Pilots not used to extremely maneuverable 3D aircraft, and the use of large amounts of expo may also chose to program dual rates with significantly less throw. Aileron: Elevator: Rudder: 2 1/2" (64mm) up 3" (76mm) up 3" (76mm) left 2 1/2" (64mm) down 3" (76mm) down 3" (76mm) right The throws below are the same as those used by Quique Somenzini (used with the expo values shown at the right). Aileron: Elevator: Rudder: 36 3" (76mm) up 4" (102mm) up 4" (102mm) left 3" (76mm) down 4" (102mm) down 4" (102mm) right Quique Somenzini’s Competition Radio Setup These numbers represent the exact radio setup programmed into Quique’s personal 9303 transmitter to control his Byp Yak, using only 1 flight mode. Set the travel settings on all flight control channels (Aileron, Elevator, and Rudder) to approximately 140–150%. Make sure you do not overdrive the servos causing stalling of the servos and excess current draw.
